Guthrie Govan, Paul Gilbert, Steve Vai and Joe Satriani are good imo.

Buddy Guy is a contender and still going strong at 86. Seen him about 20yrs ago at Glastonbury, was fecken awesome. https://www.youtube.com/results?search_query=buddy+guy&sp=EgIIBQ%253D%253D

Maybe Jimmy Page, Eric Clapton, or Slash?
